Hi Ali,
Ali Khan said: This typical application getting signal from secondary winding of ignition coil(correct me if i am wrong). I believe that's why there is a voltage divider to reduce input voltage for TACH+ pin. While I have already converted 12Sq…
Part Number: LM2917-N Tool/software: Dear Sir/Madam,
1) Whether can we make use of LM2917MX-8/NOPB for the application of PWM signal (where Duty cycle will be varying) to voltage conversion?
2) If this PN is not suitable then could you please share…
Part Number: LM2917-N Tool/software:
I am trying to push 1Khz-10Khz 0-5v Square-wave from my PLC and output between .8v -4v DC. I have the signal coming in I just do not seem to be getting voltage out. I KNOW I am doing something wrong. Any thoughts…
Part Number: LM2917-N Hi,
I intend to use LM2917 to read RPM of motorbike on an MCU by reading analog voltage by following circuit.
I want to remove the meter from this reference diagram and read the RPM on any MCU by reading analog voltage. From…
Part Number: LM2917-N Hi,
Just to be double sure some guidance is needed to validate the circuit as much help is not available. This tachometer and speedometer would be for motorbikes only. For speedometer hall effect sensor is used and for tachometer…
Part Number: LM2917-N I'm using the LM2917 in 14 pins package, I can't make it work, maybe you can draw me the correct schematics for a pulse from 0 to 2.3Khz 0-5v
that I would lkie to measure using a 3.3V A2D, I'm currently using 24V as input voltage…
Part Number: LM2917-N Hi. Page 15 of the datasheet shows the output response time to a change in Freq at around 250ms with the stated component values. Is it possible to decrease the response time to below 30ms? I calculate Vripple to be 10mVp-p @ Fin…
Part Number: LM2917-N Hi,
My customer has the following question about the LM2917-N.
1. What are the frequency limits (highest and lowest)?
2. What is the output type, AC or DC?
3. If AC output. The Input frequemcy=out frequency? What is the output…
Part Number: LM2917-N Other Parts Discussed in Thread: LM331 , VFC32 Hi,
Please suggest a frequency to voltage converter that ll work with 10mv/Hz resolution.
Typical Application: Automotive
1. Based On hall sensor Input Reference(frequency range…
Part Number: LM2917-N Other Parts Discussed in Thread: TMAG5111 , OPA191 Hi,
Any design suggestions to determine the acceleration out of the LM2917? Basically a tachometer, a hall affect sensor (TMAG5111) input to the LM2917, input frequency range from…
